I never got a text link, so I can't find a way to directly add reviews for an individual…read moretechnician, but.. we'll make this work. Specifically, this review is a two-for one, both for Ed La Barre and Thomas McGrath who were both my latest technicians for separate calls. Ed came out to inspect and service my water heater, and while his efforts to repair the equipment I had weren't successful, he also canceled the usual charges for his labor on that call immediately, which was appreciated. Thomas came out for my club member service and inspection of my furnace, which of course cost me nothing since it's covered by membership dues and absolutely pays for itself very quickly. In both cases, these guys were polite, knowledgeable, and efficient. Absolutely top marks for both of them.

Caused my working furnace to fail, the house froze, leaking pipes…read moreand they refused to make the repairs that they caused. On October 22 2025 I had Master Services perform an annual service on my Carrier furnace. The furnace was working well with no issues but I wanted to do the annual service as recommended. Morgan the technician poked around but I did not see any of the standard procedures done like I am used to seeing from other providers. There was a tremendous sales pitch pressure from the tech spending more time on how I can purchase a new furnace from their company, even though our furnace served us well and was in excellent condition. I paid the bill and he left. Oct 24 2026 just two days after service The furnace failed to start and we were in cold weather for several hours. So I called the company back asking why the furnace is having this problem right after the tech worked on it. Morgan came back and blamed it on a blown 3A purple fuse which never happened before. He said he did not have a fuse in his truck, luckily I had 3 of those in my fuse kit in my truck so I gave him my fuses, he started switching wires around burning 2 more of my fuses and finally he got the wiring right and the 3rd and last fuse worked and the furnace started to work. He did not seem sure of what is happening or what else to check for. We had to make a trip out of state to visit family but we always leave the heat on in cold weather just to be safe and we turn the main water valve off and drain the pipes. Jan 28 2026 We returned to the house to find there was no heat in the house and the toilet tank and bowl had blocks of ice in them. The bathroom sink trap was cracked from ice and the shower valve was busted along with the kitchen sink not draining. A pipe also sprung a leak in the basement. There was also a strong natural gas odor in the house. We called again and they sent another tech Mitch who showed up with three space heaters to thaw the house plumbing out but could not get furnace started he also confirmed the gas smell to be present he said the gas coupling inside the furnace was not tightened enough from when they did the first service. He did not bother to check the ignitor but did after I asked him to check it. He said the ignitor is bad and he will call me back the next day with a price as he claimed did not have a replacement ignitor in his truck and he estimated the price would be around $600 a part that cost under $30 He left us with no heat and a gas leak while I slept in the house in the extreme cold snap in January I could have died from both the cold and the gas leak. Jan 29 2026 Mitch never called back to come replace the ignitor. I gave up and had to call ANOTHER company to get our heat working. They came over and figured the problem in 5 minutes replaced the ignitor and tightened the gas coupling which was left loose by two technicians from Master Services. My bill was $357.44 and our furnace is working well since till the writing of this review March 23 2026. Jan 30 2026 Plumber Eric from Master services came over replaced the frozen sink trap that they caused to fail from freezing and charged me $154.83 He also gave an estimate of $1700 to replace the leaky pipe that they caused to freeze up due to low quality work. I refused to do this and feel they must take responsibility and fix what they broke. I had to replace the shower valve myself and get the kitchen sink flowing again. Several phone conversation with manager Juan did not help as he insisted they have to charge me for pipe repairs that would have never happened if they did not cause the freeze. My pipe is still dripping and they totally ignored the problem. I see that a Mr. Kyle Burroughs listed as general manager on the better business bureau website so Mr. Burroughs if you are reading this Please intervene to rectify this problem. You can get my contact information from your service department records. All I need now is you send a plumber to replace the pipe section that is leaking so we can put this nightmare behind us.
